What are the open clusters?
oooo
Open clusters are loosely bound groups of a few tens to a few hundred stars.
In open clusters are loosely held together by gravity. The stars in an open cluster slowly move away from each other over time.
The Pleiades or The Seven Sisters is one of the most famous open clusters the constellation of Taurus.

All the stars in an open cluster formed at about the same time. They also formed from the same cloud of gas and dust.
This means they had the same initial chemistry. This knowledge lets us make an assumption.
Any differences between the stars in the same cluster must be due to the mass of each star.
Stars in one cluster can vary in brightness, colour, and length of lifetime.
